Crush Washers

Crush Washers for the Moss auxilliary head oil feed (for the 1500). I can't find'em available elsewhere, and since I've broken a banjo bolt before (when first installing the kit) I am pretty fearful of breaking it again. I went to my favorite hydraulics shop and sourced a pair of copper ones, but they turned out to be too thin, and the bolt bottomed before the washers crushed. When I tried to install the old crush washers with the new ones, that didn't seal very effectively either! (it stopped leaking after I tightened it pretty well, but then when I brushed the banjo, it started leaking again). I have seen aluminum washers from Earl's, but I'm not sure that they'd seal well either, because they may either be too thin, or too hard for the banjo bolt to survive the tightening. I've also seen (from mcmaster carr and fastenal) 'sealing washers' with steel outside and a rubber inside, designed to seal when tightened.

I plan to eventually convert to Earl's fittings, hose, and washers once I have the time, but I want something I can order today and install by the end of the week (friday AM), so I can finally drive the car!

P.S. After blowing a head gasket in August, I finally got around to starting it. It was tuned to idle around 900RPM hot just before the head gasket blew. Now it'll idle cold at 1250 RPM. Just goes to show that when the gasket was going, power was dropping pretty severely (and I still had the fastest time in class that day!).
 
So, double up on them????? or at least one side.
 
Take your old original crush washer(s) and heat them red hot with a torch. Let them slowly air cool and they will be soft again and should seal if they haven't been scared up.
 
Oh, I forgot about that, yep yep.
 
I tried the doubling up, guess I didn't make that clear. The doubling didn't seal after I got them really tight (and I was afraid of breaking the crappy bolt again).
 
I needed to replace the exact crush washer on my '78 when I dropped one and could not find it.

I went to the Autozone near me, and of course they don't sell them separately. In the section where they sell "HELP" brand items, they offer a pack with various size copper washers. While not a crush washer, I found one size in there that worked.

Suggestion, when I order inexpensive parts, such as the crush washer, tab washers for brakes, etc, I always order a few extra. I know I will need them eventually. I also know that if I don't have them, I will need them NOW.
If I use my last spare, I make a list and add them to my next parts order.
 
I order numerous spares, but this was from the original installation of the item. Unfortunately, when I got the replacement bolt and washers, I didn't get extras.
